PSA: If you have this shampoo, you should probably chuck it

If you’ve watched late-night TV, you’ve probably seen an advertisement for celebrity stylist Chaz Dean’s WEN hair care products. Dean, who has styled the hair of stars like Alanis Morisette, developed WEN as an alternative to your average shampoo, which Dean views as “harmful to hair” due to “harsh chemicals.” Well, despite his claims, Dean’s hair product is allegedly causing more harm than preventing it.

“WEN [is] an industry-changing product line that excludes ordinary shampoo,” reads the company’s website. “What sets WEN apart is its cleansing conditioner, a single-step process that cleanses and conditions the hair simultaneously. The cleansers include a perfect blend of special ingredients, including natural botanicals and herbs, and do not contain sodium laurel sulfate or harsh chemicals.”

The shampoo alternative, which costs $30 a bottle, has seen a surge in popularity in recent years since its debut in 2009; the hair product’s Facebook page has almost 600,000 likes, and in just its second year of sales alone, the company raked in $100 million in 2010, according to Forbes.

WEN promises to strengthen and revitalize your hair with no additives or harmful chemicals. The company has even had famous representatives like Brooke Shields on its side. However, it now looks like Chaz Dean may be in some hot water indeed, because more and more women are now speaking out about a truly awful side effect of WEN that has been leaving them in tears: their hair is falling out in massive clumps.

“I can’t leave my house,” wrote one woman in the caption of a picture she posted to the company’s Facebook page. “I’m depressed [and] WEN hair products is responsible for my hair loss. . . I’m overwhelmed and frustrated [and] I cry when I look in the mirror.”
